Test plan:
1. Run updatedatabase.pl
2. Set sysprefs MarcFieldForCreatorId, MarcFieldForCreatorName,
MarcFieldForModifierId, MarcFieldForModifierName
3. Create a new biblio
4. Verify that the fields are correctly filled
5. Logout and login as another user
6. Modify the same biblio
7. Verify that only the fields for last modifier have been modified
Works perfectly.
